PROBLEM TO BE SOLVED: To provide a rolling bearing that allows lubricating oil supplied to the rolling bearing to easily penetrate from one side to the other side in an axial direction.SOLUTION: The rolling bearing 10 includes: an inner ring 12 having an inner ring raceway surface 12a; an outer ring 14 having an outer ring raceway surface 14a; a plurality of rolling elements 16 disposed in a rollable manner between the inner ring raceway surface 12a and the outer ring raceway surface 14a; and a cage 20 having a plurality of pocket parts 22 surrounding and holding the plurality of rolling elements 16, and column parts 24 connecting the plurality of pocket parts 22. One side surface in the axial direction of at least one column part 24 disposed in the circumferential direction of the cage 20 is formed projecting to the other side in the axial direction from the other side end face in the axial direction of at least one raceway ring out of the inner ring 12 and outer ring 14. |
